To (455 whom it may concern:

Be it known that i, Josnrii H; TILLING- I 'r, a citizen of the U ni'tedStates, residing at an Francisco, in the county of San Franciscoand'State of California, have invented new and useful Improvements. inTool: ta cum-ing- Apparatus, of which the followmg is a specification. 1his invention relates to improvements in vrus for tacllitatlng thescouring vof wool and like material.

ihe primary ob ect of the mvention is to pro ide apparatus foradvancing. wool g scourin baths in a reliahle'and extious manner, andsothat largequaniesof wool maybe scoured ettfectively'and ruiickly muchmore so than when scoured with the apparatus now in use.

.Knotherand more specific object of the invention is to provideapparatus for mov ing wool through liquid from one end of a 'I said woolout of said liquid and depositing it.

receptacle to the other and then liftingupon a conveyer; the movement ofthe wool tl'irough the liquid being such as will provide tor a thoroughand expeditious scouring thereof.

The invention possesses other advantages 1 and features, somev of which,with the foregoing, will beset forthat length inithe followingdescription wherein I shall outline in full that form of the inventionwhich ll haveselected for illustration in the drawe in s accompanyingand forming a part of the present speclficatlon. In said drawmgs,

l have shown one form of the construction of a my invention, but it isto be understood that I do not limit myselfto such "form, since theinvention as expressed in theclaims may be embodied in a plurality offorms.

Referring to the drawings:

Figure 1 is a longitudinal fragmentary sectional view through a tankshowing the apparatus of my invention in side elevation and partlybroken and in section, and illustrating various positions of theapparatus in dotted lines.

Fig. 2 is a top plan view of the apparatus.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1 with certainparts omitted for the sake of clearness of illustration. Fig. 4 is asectional view taken. on the line 4-4; of Fig. 1, showing a part thereofbroken away. p r In carrying out my 1I1Y11l310l1,I mount a reciprocatingwool advancing member and that as 'many as desired may be used. 3 Theapparatus is'preierably arranged so that the advancing'n ember moves toadvance the wool through the liquid, then lifts clear of the wool andmoves back to starting position in a plane above the Wool and thenlowers into woolengaglng position. Thus the wool is intermittentlyadvanced into a p0sij tion to he lifted out of theliquidby said liftinginemher andin being thus moved is thoroughly'washedwh leadvanc n I Thepresent embed ment ofmy invention as illu'strated'in the accompanyingdrawings.

comprises a tank or vatl open on its upper side, and containinga'suitablejliquid, not

shown, for washing the wool. one tank, but in practlce I employ severaltanks contiguously arranged so that wool is mov d through one andinto'the other. Mounted to reciprocate into and out of one end of thetank 1 is awool advancing mom 7 her 2 comprising a frame 3 which isprefer:-

ably rectangular; horizontally supported,

and of slightly less width than'the space between the walls 4: of thetank whereby the the tank or vat and may move freely between sets ofspaced fingers or teeth o, the sets preferably being secured to theunder side of the frame as at 6 and depending therettrom'at the ends andcenter of the frame transversely thereof. These fingers extend acrossthe tank and are slightly spaced from the bottom? of the tank wheninoperative position. Thetrame j3'is supported just above the level ofthe liquid which level is indicated by the line'8, whereby I only thefingers are immersed in the liquid.

The frame 3 is suspended from a frame comprisinguprights 9 securedonopposite sides of the tank and a cross piece 10 secured to theuprights. Depending from the cross'piece. is a pair of hangersll havingI have shown frame extends substantially entirely across:

the fwalls. Theframe carries aplurality of bearings 12 in their lowerends for horizontal shafts 13 and 14 arranged side'by side andoperatively connected by gears 15 fixed to said shafts and meshing witheach other. Fixed to each shaft and depending therefrom are pairs ofsupporting arms 16 provided on their lower ends with rollers 17 whichride in guideways 18 therefor arranged on oppositesides ofthe frame ,3.The arms 16 normallyextend downwardly, diverging from one another andthussiipport the frame 3 in horizontal position. Crossed arms19 areiix'edto the'shafts 13 and 1 1 and extend upwardly therefrom carryingweights 20 thereon above the shafts. These weights are arranged toassist the mechanism in raising the member 2, to the dotted lineposition shown in Fig. 1. To provide for so raising the mem. er 2 andfor lowering it, a rocker arm 21 is fixed to the shaft 13 and'extendssubstantlally at 7 right angles tothe arms 16 carried by $21K shaft.This rocker arm is pivotally connected as at 22 with a IGCIPIOOEIUIIO'rod 23.

The rod 23 is operatively associated ith the main operating mechanism,which will be later described, and when pulled will rock the arm 21 androtate the shaft 13 and shaft 14 through the gears 15, causing the arms16 to lift or raise the member2 as will be later described more fully.The outer end of the rod 23 is provided with a. series of spacedopenings 2 1' which provide for ad justing the connection thereof withthe arm 21 to regulate the height to which .the member 2 is raised. V i

The member 2 is reciproceted and raised and lowered by operating meanscomprising frame 25in which. is journaled a shaft 26. Pulleys 27 arefixed to this shaft and support belts'27 driven from a suitable sourceof power, not shown. The shaft as has pinion 28 thereon which mesheswith a. pinion-29 on a shaft 30- also journaled in the frame 25 andwhich extends across the tank 1. A. preferably rectangular operatingframe 31 is pivotally suspended from the shaft 26 by suitablemeans32which permits the frame 31 to swing backand forth. The

shaft 30 extends through the central point in said frame. 31' and has aneccentrica'll mounted circular disk 33 fixed thereto so as to engageopposite.longitudinal Sides 34 the frame,-said frame being channeled toreceive the eccentric33. Thus as the shaft 30' and eccentric 33 rotate,the frame is swung back and forth as indicated in dotted lines inFig. 1. This frame 31in swinging back tain ends, as at 3?,"50 the frame3 of the member 2, and at their other ends are p1v-- 1 oted, as at 38,to arms 39 extending downthrough the liquid.

of the drawing. As the frame 31 wardly from and rigidly connected withsaid frame, whereby when the frame swings, the member 2 willreciprocate.

he wool lifting member comprises a shaft 40 rotatably mounted in abearing 41 on the lower ends of the arms 39. Spaced tines or liftingfingers 12 are secured to the shaft d0 and eitend outwardly at rightangles thereto. The tines or fingers are arranged to extend across thetank, as are the fingers 5, and normally lie in horizontal position, asshown in full lines in Fig. 1. To provide for rotation of the shaft 10so as to effect a lifting of the wool with the fingers 42, a rocker arm43 is fixed to the shaft and has an adjustable pivotal connection llfwith a rezoxiprocating swinging rod 415. This rod 15 is slotted as at46 at its upper end and slidab'ly and pivotally mounted on the shaft 30by provision of such slot. A cam is fixed to the shaft 30 and rotates so21.5110 engage a' roller 48 jon the rod 45. A weighted arm' 19 is fixedto the shaft 10 and has tendency normally to rotate the shaft so as tomove the tines42 into down position, this. tendency being normallyovercome by the rod and rocker 13, cam 47 and roller 48. The tines 1-2during the operation of the machine areadapted to extend over a conveyer50 as shown indotted lines in Fig. 1, which ismounted between the wall aof the tank and leads to another tank notshown.

The means for reciprocating the rod 23 to raise and lower the member 2comprises a cam 51 fixed to the shaft 30 and bearing upon a roller 52carried on a slotted guide member 53. The guide member is slidablyconnected upon the shaft and at one end is connected'as at 54.360 therod 23. The other end of this member is bent back upon itselfto providea hook portion The slot in the guide member opens out through this hookend whereby-thesh'aft 30' enters and leaves this open end. The cam"roller 52 is journaled in said hook end and, when the cam rotates thisvroller in engaging the cam the machine is as follandfls'ut ferg'ed. inthe liquid therein, so that it will be secured in being moved Assumingthat "the apparatus is'in the position shown in full lines in Fig. 1,upon rotating the shaft 26, the shaft 30 is rotated in the direction ofthe arrow, shown in F 1, by the gears 28 and 29 on the respectiveshafts. At this time, the cam 51 is in such posit on thatwhen the of theoperating frame 31 into the right hand dotted line position shown inFig. 1 swings to right hand position, as shown in dotted lines theright, the Wool advancing member 2 is moved to the right through the rod36 cone through the wool and effect a scouring action. After the shaft30 and eccentric 33 have made one quarter of a revolution, the frame 31has been swung toits outermost in'Fig. 1, and the member 2 has beenlifted so that the fingers 5 are clear of the liquid in the tank, asshown in dotted lines in said figure.

said guide and rod 23 attached thereto will be'moved to the right, suchmovement rocking the rocker arm 21 and rotating the shaft 13. Byrotatingthe shaft 13, the gears 15 on the shafts 13 and 14 provideforrotation of the shaft let also, and the arms 16 are moved away fromone another, causing the rollers 17 to move outwardly intheguidee ways18 and the frame' 3 to belifted. The weights 20 on the arms 19 assist inthe lifting of the frame 3 by exerting a tendency to rotate the shafts13, 1 1, thus it will be seenthat the wool advancing member 2 moveshorizontall r inthe tank to advance the wool in front of the fingers 5and is then position until the end of this backwardmovement of themember 2 is reached, at which time the cam engages the roller 52 so asto push the rod 23 and rock the arm 21 whereby the shafts 13 and 14 willrotate so as to cause the member 2 to descend into the tank intoposition to engage and advance the wool. At the time that the member 2is descending into starting position the frame 31 has swung into itsextreme left hand position, shown in dotted lines in Fig. 1 and thelifting member 35 has been brought into position to lift up the wooladvanced by the member 2 during the previous advancing movement of saidmember 2. As said frame 31 swings to the left, the cam 17 moves so thatthe roller 18 which it engages will move freely over the cam so as topermit the rod 45 to move upwardly. This rod has a tendency to moveupwardly at all times when the weight 19 is in up position, as shown inFig. 1 of the drawings, and when the cam 47 permits said rod to moveupwardly, the

weight will gravitate and by so doing ro- The cam 51 is so shaped thatin rotating against the roller 52 on the guide'53,

tate the shaftf30, so as to bring the fingers 12 fromsubstantiallyhorizontal position into substantially vertical position, such as shownin dotted lines in Fig.1 of the draw ings, and behind the wool advancedby said member 2. e As the member 2 begins to advance horizontallythrough the liquid, the cam ,47 bears upon the roller d8, so as todepress or push downwardlythe arm. 45 with the result that the shaft 40is rotated so as to, lift the tines or fingers 41-2, and when solifting, the fingers will pick up the wool in front thereof. During thislifting up of the fingers, the frame Sibegins to swing back toward theright and this moves thejfingers bodily .in an arc toward theright,;while said;

horizontal position. 'With this operation, the fingers scoop up thewooland. carry it forward; so that when the frame L1 moves to itsfurthermost right hand position,.said

fingers will ezgtend over the adjacent end of the conveyor 50anddepositthe. wool lifted thereby on to said conveyor. At the time thatthese fingers extend over the conveyor. 50, the roller 48engages'in,anotched sui face57 on said cam 47 and l3l18'IOCi'ff5. is.

permitted to have a quick upward move ment wh ch results in causing thefingers 42 I to "snap downwardly'upon the conveyer and the wool is thusquickly disengaged from the fingers immediately after; this snapping;

down of the fingers 7 on the conveyor. I The, frame 31 is swung backtoward the left,

through action of the eccentric33- and the ,fingers aremoved clear ofthe wool and iconveyer. vIt will thus beseen that the mem;

her 2 has a substantially rectilineal motion,

tank and then lifts clear of the tank perpendicularly, moves back tostarting posi-,

tion and then lowers perpendicularly back into the tank. This operationbeing continuous, the wool is advanced intermittently, and in being thusadvanced, the liquid in Wool in such a manner that effective scouring ofthe wool is supplied. The cam opoperating means is of simple compactform, 4

' utilizing comparatively little power to op erate effectively. Theoperating means in.

view of its simplicity, and particular arrangement is reliable, positivein operation and capable of operating continuously with out becomingderanged.
